Care
The Tentacled Blenny is a hardy species that adapts well to life in captivity. It requires an aquarium with plenty of rockwork and hiding places to feel secure. This species is an omnivore and will accept a variety of foods including frozen and live meaty foods, as well as some vegetable matter. It is important to maintain high water quality and stable parameters to keep these fish healthy.
Reproduction
In the wild, Tentacled Blennies are oviparous, with males often guarding and aerating the eggs until they hatch. Breeding them in captivity can be challenging, and hobbyists aiming to breed them should provide a separate breeding tank with optimal conditions.
Habitat
Parablennius tentacularis is native to the Mediterranean Sea and the eastern Atlantic Ocean. It is commonly found in shallow, rocky coastal areas where it can hide among the crevices. This species is well-suited to the rocky environment of a reef aquarium.
